Cirrus Design CORP SR22 accident near Knoxville, Tennessee, December 16, 2021

The NTSB's narrative final · quoted from the NTSB record

According to the pilot, the event occurred on final approach when the airplane encountered wake turbulence from a landing Airbus A320. The pilot reported feeling a sudden bump, leading to an extreme roll of approximately 135°. The pilot instinctively applied corrective control inputs and commanded the pilot-rated passenger to pull the Cirrus Airframe Parachute System (CAPS). The passenger reached for the handle and pulled it just as they reached a near-level wing attitude with the nose pitched down. The pilot felt the deceleration of the parachute for a couple of seconds before they impacted the ground. A postimpact fire ensued and both occupants evacuated the aircraft. The pilot was seriously injured, and the passenger received fatal injuries. A review of Air Traffic Control (ATC) communications revealed that all instructions and advisories were acknowledged by the flight crew of the Airbus and the pilot of the Cirrus as appropriate; however, ATC failed to provide a wake turbulence cautionary advisory to the pilot of the Cirrus as required by Federal Aviation Administration (FAA) order JO 7110.65Z, Air Traffic Control, for simultaneous same runway operations involving a small aircraft landing behind a large aircraft. Although the pilot was aware of the preceding Airbus, the very purpose of this advisory is to remind and emphasize to pilots the potential for dangerous wake encounters.
